Design Techniques and Applications of Ionic Liquids Incorporated Metal Organic Frameworks (IL/MOFs)

Metal-organic frameworks (MOFs) are an interesting class of materials consisting of central metal ions and organic binders. These are porous crystalline materials in which different organic groups are combined with metal that has been cemented into place to provide a rigid and porous geometry. Green Metal Organic Frameworks (GMOFs) are a novel class of porous materials with a number of distinctive properties, including uniform and tunable pore size, large surface areas, adaptable pore structure, high porosities, acceptable thermal and chemical stabilities, simple production, and structural diversity. In order to alter the physicochemical characteristics and gas affinities of MOFs, ionic liquids (ILs) have recently been inserted as cavity occupants into the pores of metal organic frameworks (MOFs). Recent research has demonstrated that IL/MOF composites outperform pristine MOFs in a variety of applications, including gas storage, membrane-based gas separation, adsorption, catalysis, and ionic conductivity. Ionic liquid-modified MOFs (IL/MOFs) composite materials benefit from the high stability and versatile physical and chemical properties of ILs while retaining the structural characteristics of MOFs. Scholars are particularly interested in them because of their vast potential for usage in the domains of isolation and investigation. In this review, we provide a comprehensive overview of the applications of IL/MOF composites and talk about the latest advancements in their synthesis. The benefits and drawbacks of employing IL/MOF composites in diverse applications were investigated in order to ascertain the future directions in this field.
